1,053,633 2/1913 Mundy 52/200 X 5 Claims, 2 Drawing; Figures PATENTED 74 sum REF 2 SKYLIGHT This invention relates to a skylight having a rim which is secured to a roof or like and a transparent or translucent window is attached to the rim.

It is known to ventilate skylights by raising the trans parent or translucent window. Moreover, it is also known to provide ventilators of different types in the rim in order thus to bring about an air flow between the ambient air and the air inside the skylight so that the window does not mist and no dripping water forms on the window.

However, known skylights having ventilators in their rims have the disadvantage that their rims have to be relatively high, so that emerging air flow does not fall directly onto the adjacent roof surface. Furthermore, they have the disadvantages that rain water can penetrate through the ventilation aperture from outside and that temperatures at the aperture are different from those on the remaining parts of the rim whereby condensation can again form.

An object of the present invention is to provide a skylight in which ventilation is afforded without disadvantageous effects on the adjacent roof surface, without the formation of condensation and wherein the penetration of rain wateris obviated r minimized. A companion object is to provide a skylight having a rim which is relatively low in spite of the built-in ventilator.

Accordingly the invention provides a skylight comprising a window, an attachment rim whereby the window is attached to a roof or like structure, and a ventilator aperture in the rim, adjacent the ventilator aperture, an upstanding wall which terminates above the level of the ventilator aperture and above a flange projecting outwardly from the rim is disposed above the upper edge of the wall, the space between the rim and the wall and between the flange and the upper edge of the wall defining a channel for outgoing air.

Advantageously there is arranged on the outwardly projecting flange a downwardly hanging swingable flap, a lower edge of which normally lies on the outer surface of the wall.

It is furthermore advantageous to provide, a rain backwash nose on the outer wall surface, under which rose the lower edge of the flap may engage in its normal position.

A further object of the invention is to provide a skylight wherein a window thereof is securely connected to an attachment rim in a simple manner.

The invention will be described further, by way of example, with reference to the accompanying drawings:

FIG. 1 is a fragmentary cross-sectional view of a pre ferred embodiment of skylight conforming to the invention;

FIG. 2 is a cross-sectional view, on an enlarged scale, of a rim of a skylight similar to that of FIG. 1.

In order to ventilate a preferred embodiment of skylight conforming to the invention, a skylight window 1 is securely connected by a suitable clamp 3 to an attachment rim 2 securely connected to the roof. A ventilation aperture 4 is provided in the wall of the rim 2. In front of the ventilation aperture 4. outside the skylight, there is provided a wall 5 which projects upwards above the top of the air outlet aperture 4 of the rim 2. The upper edge of the wall 5 has spaced thereabove flange 6 projecting outwardly from the upper edge of the rim 2. The space 7 between the rim 2 and the wall 5, as well as between the flange 6 and the upper edge of the wall 5 serves as an air channel along which air can flow in the direction indicated by the arrows.

On the free outer edge 8 of the flange 6 there is arranged a depending flap 9 swingable about its upper edge portion thereof. In the normal or rest position of flap 9, its lower edge butts against an outer surface of the wall 5, the lower edge portion of flap 9 being inwardly bent so as to engage under a rain backwash nose 10 arranged on the outer surface of the wall 5.

Spaced inwardly from the backwash nose 10 is a sec- 0nd rain backwash nose 11. The two rain backwash noses 10, 11 have the task of checking rain water impinging from outside and preventing or discouraging it from running up the outer surface of the wall 5, so that rain water cannot get into the air channel 7 and thus into the skylight.

As shown particularly in FIG. 2, the flap 9 can be connected also to an electro-magnetic device 12, so that the maximum possible angle of opening of the flap 9 can be positively controlled.

The inner surface of the wall 5 is hollowed out level with the bottom of the air inlet aperture of the rim 2, and a transverse or radial flow blower 13 is mounted in the space. By this arrangement and the use of the transverse or radial flow ventilator 13, the rim 2 can be kept relatively low. Since the wall 5 extend upwardly to a distance above the roof, no low temperature area can occur at the ventilation aperture and thus no condensation can take place here. The flap 9, in conjunction with the rain backwash noses l0 and 11. prevents any penetration of rain water from outside.

Advantageously, the rim 2 is integral with the wall 5. This integral unit can be mounted by being superimposed onto a ring which forms the lateral boundary of the opening in the ceiling or roof 15. The ring 14 can serve as lost shuttering and can be concreted-in during formation of the ceiling or roof [5. By this means, a smooth termination relative to the roof 15 is afforded. The inner wall of the ring is designed in such a way that it extends rectilinearly relative to the inner walling of the rim 2. For fastening of the rim 2 to the ring 14, the ring has a flange 16, which grips behind an annular adjoint piece 17 of the rim which forms, at the same time, a seal with insulation 18. The flange 16 and the ring adjoint piece 17 are securely connected together by screws 19 or the like.

I claim:

1. A skylight closing a roof opening including a window and rim means encircling the roof opening for attaching the window to the roof in spaced relationship, said rim means including a ventilator aperture therethrough, the improvement comprising an upstanding wall substantialy parallel to and spaced outwardly from the rim means, the upper edge of said wall being located above the level of the ventilator aperture, a flange projecting outwardly from the rim means and extending across the upper edge of said wall and spaced from such upper edge, the space between the rim means and the wall and between the flange and the upper edge of the wall defining an outgoing air passage.

2. The skylight defined in claim 1, and flap means pivotably mounted on said flange for bridging the space between the flange and the wall upper edge in its norof the wall including a second rain backwash nose spaced from the first rain backwash nose.

5. The skylight defined in claim 1, the wall being integral with the rim means, and a ring lining the roof opening having an inside wall co-planar with the inside wall of the rim means.
